This application March AThis application isv iled as a continuation of my pending application, ser. No. 689,312 for Botle cooler, filed September 13, 1933 and allowed January 18, 1934.

This invention relates to bottle cooling, apparatus in general; and more particularly to apparatus 1 for cooling bottles having substantiallyI cylindrical bodies.,` The main object of the invention is to provide abottle cooling apparatus of the mechanical refrigeration `type designed to cool any desired number of bottles and their liquid contents and to maintain them automatically at any desired temperature. f

Other objects of the inventionwill become) apparent as the detailed description thereof proceeds. i In the drawing: Figure 1 is a central vertical section through acooling cabinet embodying the present invention;

Figure 2 is a perspective view of a bottle cooling unit forming an essential part of the present 'invention and shown as detached yom the cabil stalled in'a cabinet 1 having the usual top, bottom, back and side walls, properly heat insulated The cabinet forms a cooling chamber 2 `to which access may be had through a door 3 suitably hinged to permit such access. y.

Within the chamber 2 there is installed a bottle cooling unit designated generallyby the reference and 9, in which are arranged the coils 10, 11, 12, 13 and 14, respectively, the latter being shown comprise separated wallsi of conducting material enclosing the respective coils 10-to 14, inclusive,

' No. 1,824,158, september 22, l193i. Afs disclosed in said patent, the compartments formed by the separated walls of -the aforesaid plates are evac uated` so as to cause the opposed walls to colthe lower face of the plate '5.

ceptacles is preferably made of timed brass and in the manner disclosed in UnitedStates Patent -17, 1934, soi-iai No. 716,193

14 claims'. `icl. isa-12s) coils to form with the coils. I. e The opposite sides of the plates 5, 6, 7, 8 and 9 are cooled by the flow of any suitable liquid intimate heat conducting-contact l refrigerant through the coils contained in the so' plate compartments. l eral coils 10 to 14 are arranged in series sov that the refrigerant entering the top plate 5, through. the refrigerant connection 15, flows through all of rthe coils and emergesl vfrom the bottom of the unit through the exit connection 16. It is to be understood, of course, that the connections 15 and 16 are' connected to a. compressor of any suitable type for'condensing and effecting proper circulation of refrigerant fluid, under the usual thermostatic control, through' the coils enclosed in the several plates. Y

As shown in -Figure 2 of the drawing the lower face of the plate 5 has suitably secured thereto a series of substantially cylindrical bottle receivi ing receptacles 1'7. Each receptacle is suitably connected in intimate heat conducting relation ,to

shaped to form spring sleeves of a size adapted to ypermit the reception of standard sized` bottles having substantially cylindrical bodies. 'Each bottle receptacle 17 is suitably welded or otherwise secured in heat conducting relation to the lower face of the plate 5 along a line substantially parallel tothe axis of the receptacle. Diametri- As shown in Fig. 3, the sev- Each `of these rel. 1

cally opposite to its line of connection to the plate 5 each receptacle is split so as to yield to compensate for slight variations in the diameters of the bottles adapted to be inserted therein for The outer end 18 of each receptacle 17 is preff erably iiared or made somewhat bell-shaped to facilitate insertion'of a bottle therein. A strap 19,'extending along the rearward edge of the 'plates 5 to 9, inclusive, and suitably secured to said edges serve as a stop to limit the insertion of the bottle in the receptacle 17 and to brace the series of vacuum plates properly spaced apart from each other in the unit.

The upper face of theplate ispprovided with a series of bottle receptacles 1'7 secured thereto in the same manner `as the receptacles are secured to the lower face of Athe plate 5. The row of receptacles lsecured toV the plate- 6 is separated slightly from the row secured to the plate 5; and

eachreceptacle contacts for heat conducting purl Y poses `with the plate to which itis connected, but

is out `of contact with the adjacent bottle receptacles. Rows of, receptacles of the type just 'delio ' cal heat conducting bottle and sputiengthwise sate for variations in serted therein.

scribed are similarly secured in the spaces between the plates 6 and 7, 7 and 8, and 8 and 9.

The arrangement of plates and bottle receiving receptacles maybe varied as found convenient. It is not essential that the rows be arranged to faceleach other vas shown in the drawing, nor that 'they'Y should be limited to' any particular number of rows. It is obvious that any desired number of bottle receptacles might be`arranged on the upper face of the plate and on the lower face of the plate 9 providing the size of the. cabinet /will permit 'such arrangement, and it is found desirableto use such construction..

The unit is intended to'loe controlledhthermostatically so as to cool the bottles arranged thereln to any desired temperatiiife. For the purpose of connecting the capillary bulb ot a thermostatic switch to the unit each of the coils is provided with a small sleeve adapted to serveas a contactor for the capillary .Y control. The compartments formed by the` several plates are" supported by 'staggered braces 20, 21,22 and 23. Y lt is thought that the yinvention and numerous `oi its yattendant. advantages will be understood 'from the foregoing description, and it is obvious that numerous changes may, be madein the form, 'construction and arrangement of the several parts without departing from the spirit or scope of my invention, or sacrificing any of. its attendant advantages; the form herein described being a preferred embodiment for the purpose of illus- Atrating my invention.
